Buick Oil Specifications

Browse Buick models and engines. Each vehicle entry shows its current specification review status.

Choose the matching vehicle

Start with the model year and engine shown below. Confirm the engine and market in your owner's manual before using a specification; a model name alone may cover different requirements.

Entries marked “Evidence review pending” are still being checked against manufacturer sources. Open an entry to see its review status and available sources.

Find your engine code or compare oil standards. The standards checker does not establish an oil's suitability for a particular vehicle.
